How to be happy: life without suffering

The ultimate goal of everything we do is to be happy in life. It could be as simple as enjoying a succulent meal or it could be as grandiose as changing the world. One may seem more noble than the other according to the society’s opinion but the motivation behind both actions is the same - we want to feel happy. If everything we do is to be happy in life, why are we still so unhappy 90% of the time? Why isn’t being happy the constant state of being for us? Instead, so many people suffer from anxiety, fear and depression.
